Comet meets Galaxy

Submitter: Albert van Duin
Description: On the night of April 2nd, comet C/2011 L4 (PANSTARRS) was very close to the Andromeda Galaxy (M31), a rare photo opportunity.

On a visit to Rik ter Horst in Ewer in the north of the province of Groningen, I was able to take 30, 30 second images with my Canon 5D MkII. The camera was set to 800 ISO, a 200mm F/2.8 lens was used, and the camera was on a sky-tracking mount. The sky was quite dark and the comet was even visble to the naked eye. In binoculairs it was a beautiful sight.

At home, dark-, bias- and flat-frames were made and the images were calibrated and stacked with ImagesPlus, and post processed in Photoshop. Due to the low position in the sky, the image lacks a bit of blue.
